New results of an analytical study of translational nonequilibrium in a shock wave are presented that are associated with the use of the exact expression for the longitudinal kinetic temperature T x in a simple gas. It is shown that the relative magnitude of the overshoot effect for the distribution function of the pairs of molecules inside the shock front satisfies the principle of independence from the Mach number. Asymptotically exact expressions are obtained for the effect of high-speed overshoot of the pair distribution function: “light” -“heavy” component.
